BUFFER DEVICE FOR DOORS.

Application filed J'u1y18, 1914c.

To all whom i may concern.

. Be it known that l, ARTHUR SAM CHES- TON, subject of the King of Great Britain, residing at 24 Norman road, Northfield, Biriningham, England,,have invented certain new and useful Improvements in Buffer De vices for Doors, of which the following is a specification.

able attachment plate and arranged to engage with a similarly shaped recess in the fixed frame. The buffer may, however, be upon. the fixed frame instead of upon the door itself.

Figure l of the accompanying drawings shows the application of the invention to a motor-car door, the'device being represented in section. This view shows the door partly open. Fig. 2 shows how the buffer (repra sented in plan) engages within the recess in the door pillar when the door is closed. Fig. 3 is a section online as, Fig. 2, with the buffer partly in elevation. Fig. 4 illustrates a perspective view of the buffer as fitted to the edge of the door.. Fig. 5 shows the recess in the standing door'pillar to receive the buffer. Fig. 6 represents the at tachment plate with the buffer (shown separately with its fixing screw) removed.

Secured within a recess in the rabbet of the said door 1 is an attachment plate 2'provided with a semi-circular wall or flange 3 which fits thesides of the said. recess. This attachment plate 2, which is secured by screws a, is provided with a circular boss or collar 5 surrounding a central internally screwed hole.

Rotatably mounted upon the plate 2, by means of a screw 6 taking into the screwed hole in said plate, is a circular buffer 7 made of rubber, felt, or similar material, and in the form of a roller. This butler closely fits the semi-circular wall 3 of the plate 2,

side of the said buffer is also recessed to receive the boss or collar 5. If desired the hole through the buffer may be suitably hushed. v

The rabbet of the fixed or standing door post 9 formed with a semirircular recess within which is fitted a curved. wearing or shoe plate or liner 10 carried by a plate 11 secured by screws.

When the door is closed the buffer 7 engages with. or rolls into the semi-circular sh0e-plate 10 and holds the door in position, as the buffer is prevented from any vertical or lateral movements, thus preventing the door from rattling and also taking the weight off the hinges.

If desired the buffer roller may be carried by the fixed door post 9-, and the edge of the door fitted with sunken. shoe or plate to receive the said buffer.

Preferably one of the silencing devices is fitted near the top of the door and another near the bottom.

It is found by this invention that much greater latitude can be allowed for the fall of doors than usual, and in the case of side entrance and two-seater cars it will prevent the boxing on the standing pillars from becoming split.

Having fully described my invention, what I desire to claim and secure by Letters Patcut is 1. The combination with a hinged. door, and a fixed frame coiiperative therewith, of a yielding roller mounted upon the edge of one part and rotatable on an axis substantially radial tothe axis of thedoor hinges, the other part having a substantially semicircular recess to receive one side of the periphery of said roller and thereby position the door.

'semi circular-recess in its edge with which the roller does engage, substantially as described.

3. The combination with a hinged. door, and a fixed frame coiiperating therewith, of a plate secured to the one part' and having an axis radial to the door hinges and carriecl by the-attachment plate and a substantially semi-circular wearing plate carried by a side plate let into and secured Within a recess in the rabbet of the door :Erume so as to be adapted to be engaged by the roller.

Intestimony whereof I have hereunto set my hand in presence of two subscribing wit- AR'IHUR Sills/i GHES'LON. Witnesses:
